Although several surface proteins have been identified as vaccine candidate, they failed to induce sterilizing immunity and cross protection against different serovars. Thus, identification of highly immunogenic antigens that are conserved among pathogenic serovars would be first step towards development of universal vaccine for Leptospirosis. Here we used reverse vaccinology pipeline to screen core genome of pathogenic Leptospira spp.in order to identify suitable vaccine candidates. Based on properties like sub cellular localization, adhesin, homology to human proteins, antigenicity and allergenicity, 18 antigenic proteins were identified and were further investigated for immunological properties. Based on immunogenicity, Protegenicity, Antigenicity, B-cell and promiscuous T-cell epitopes, 6 Potential Vaccine Candidates (PVCs) were finally selected which covered most of the aff...

This task often consumes a lot of time, efforts and other resources. The research community have devoted considerable amount of efforts to address this problem by proposing many techniques for automated vulnerabilities detection and fix generation for web application. Many of these techniques can reliably detect vulnerabilities and generate fix(es), which can be applied to the web application’s code, by the developer, for possible fixing of the vulnerabilities. Hence, the actual code modifications that fix the vulnerabilities is not automated and has to be carried out manually. To the best of our knowledge, none of the existing automated techniques is able to do this, and hence the actual fixing of the vulnerabilities is left for the human developer to handle. In this paper, we propose a novel framework for automatic vulnerabilities fixing f...

Dengue is an acute febrile illness but sometimes causes more fatal complications like dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS). Delhi, the capital of India has become hyper endemic for dengue virus because all the four serotypes are circulating here. The present study describes the identification of dengue virus from clinical samples collected from the suspected dengue patients from New Delhi, India during 2016. The CprM region of Dengue virus genome was analyzed for phylogenetic, selection pressure and Shannon entropy analyses. The present study reports circulation of a single serotype (DENV-3) in New Delhi, during 2016. The phylogenetic analysis revealed that Indian subcontinent (genotype III) of DENV-3 was circulating in Delhi during this period. Neutral selection pressure in the analyzed region revealed relatively conserved nature of this ...

Concurrent infections are reported due to co-circulation of these pathogens, especially in endemic regions. We report a rare case of triple infection with 3 arthropod-borne pathogens (Plasmodium vivax and the dengue and chikungunya viruses) in a 3-year-old child from New Delhi, India, in August 2016. The viruses were identified by RT-PCR and the parasite by microscopy and antigen detection. The dengue virus serotype 3 sequence was clustered in the genotype III by the phylogenetic analysis. Mixed infection with multiple pathogens is a challenge for accurate diagnosis due to the overlapping clinical symptoms. The accurate and timely diagnosis of multiple pathogens in such cases is important for rapid and effective patient management.

The devastating effect of Zika viral infection is reflected by its neurological manifestations such as microcephaly in newborns. This scenario evoked our interest to uncover the neurotropic localization, multiplication of the virus, and the mechanism of microcephaly. The present report provides an overview of a possible molecular mechanism of Zika virus-induced microcephaly based on recent publications. Transplacental transmission of Zika viral infection from mother to foetus during the first trimester of pregnancy results in propagation of the virus in human neural progenitor cells (hNPCs), where entry is facilitated by the receptor (AXL protein) leading to the alteration of signalling and immune pathways in host cells. Further modification of the viral-induced TLR3-mediated immune network in the infected hNPCs affects viral replication. Downregulation of neurogenesis and upregul...

Dari sudut lokasi geografi pilihan raya, majoriti mereka tinggal dan sebagai pengundi di 4 kawasan Dewan Undangan Negeri (DUN) Sarawak iaitu Belaga, Ba'kelalan, Telang Usan dan Batu Danau yang berkedudukan di bahagian tengah, timur dan utara pedalaman Sarawak. Faktor keterpencilan dan tidak terdedah dengan arus pemodenan menyebabkan pandangan politik mereka jarang kedengaran dan terpinggir. Namun demikian, golongan muda Orang Ulu yang berpelajaran serta berhijrah dari perkampungan asal mereka telah mula merubah pemikiran seterusnya cuba beradaptasi dengan majoriti masyarakat luar yang berfikiran terbuka. Justeru, adalah menjadi tujuan artikel ini untuk menganalisis politik Orang Ulu dari sudut partisipasi dan persepsi mereka ketika pilihan raya DUN Sarawak 2011. Berdasarkan soal selidik dan pemerhatian di lapangan menunjukkan bahawa 83.8 peratus menyatakan gagasan "1 Malaysia: Rakyat Didahulukan, Pencapaian Diutamakan" disokong, dihayati dan dimanifestasikan oleh pengundi. Dari aspek governans pula, 68.8 peratus responden menyatakan Indeks Petunjuk Prestasi (KPI) untuk wakil rakyat dan Menteri adalah baik dan mempengaruhi sokongan rakyat terhadap kerajaan dan dasar/pembaharuan yang dilakukan oleh kepimpinan Perdana Menteri dalam memantapkan pembangunan negara terus mendapat sokongan rakyat. Dari sudut tingkahlaku politik, jika dilihat kepada status pendaftaran sebagai pemilih/pengundi, 78.0 peratus menyatakan mereka sudah mendaftar sebagai pemilih. Seterusnya, 5.0 peratus menyatakan mereka menganggotai parti politik PBB, 13.8 peratus menyertai SPDP, 8.8 peratus merupakan ahli PRS, 3.8 peratus menjadi ahli SNAP dan 5.0 peratus merupakan ahli PKR dan 63.8 peratus menyatakan tidak menyertai mana-mana parti politik. Responden menjangkakan BN akan berjaya mengekalkan pemerintahan di Sarawak.

It is cultivated wild areas on village outskirts and wasteland in Malaysia, Perak State. The parts of the plant are used for diuretic, mild laxative, cholerectic, hypotensive, lowering blood pressure and treatment for cardiac and nerve diseases and cancer. So far no phytochemical and biological investigation has been carried out on this endangered and rare species, though several ethnomedical uses of the plant exist. The present study aimed to carry out antibacterial properties of the methanolic extract of H. sabdariffa leaves and fruits. The crude methanolic extract of H. sabdariffa leaves and fruits showed better antibacterial activity against Gram negative bacteria compared to Gram positive bacteria. However, the standards showed better activity with lower concentration when compared to both the extracts against the entire organism.
